Endoscopic Approaches to Cricopharyngeal Myotomy and Pyloromyotomy.

Endoscopic cricopharyngeal myotomy has been demonstrated to be a safe and efficacious procedure with favorable outcomes for the treatment of cricopharyngeal dysfunction with or without Zenker diverticulum. It is a less invasive approach with decreased morbidity compared with the open approach and minimal reported complications. Peroral endoscopic pyloromyotomy is a novel technique for the treatment of gastroparesis. It has shown promising results in terms of its safety, complication profile, and symptom improvement in a minimally invasive approach that is appealing to many patients. As further data emerge on the technique, long-term efficacy of the procedure will be better understood.
